How to handle Mould Maintenance - Part 2

[JAFDias]

Hi all!

Due to the fact of the thead711-102634 is now closed, i intend to reopen it questioning what kind of information do you consider helpful to be in a mould maintenance data base (Preventive and corrective maintenance).

Ex:

1-Mould code;
2-Part(s) code;
3-Drawings;
4-Spare parts;
5-Nr of shots up-to-date;
6-Insert change history;
7-Insert change type (in the presse or in the table);
8-PM plan (operations and nr of cycles to PM action);
9-PM plan manager;
10-...
11-... What else do you sugest?


I'm actually using IFS application (

http://www.ifsworld.com/uk/)

but i need to feed it with information.

The main problem i'm dealing with now is due to the nr of shots up-to-date. The field is been feeded with the quantity of parts produced. However, when the mould is a family mould or a multicavity mold, that number is increased, turning false the informations of nr of shots.

In arround 800 mould to manage, i can't do it manually.

Any sugestion?



Thanks a lot

Multiply the number of shifts the mold was in a given machine by the number of machine cycles possible in a shift, and record that.

I know when I had family tools or multi cavities tools and the shot counts were total parts, put a field in your database for No of Cavities and just divide total parts by cavity.
You will also want to have Last P.M. Date, Performed By; Findings. included in your database.
Since I am an Access Database programmer I have always used Access for my P.M. plans, but any good database with a usable front end will work.
You still have to remember that you want good data put into the system so you can get good information back out.
At Rubbermaid I was responsible for over 1000 molds and the Access database handled all the information for at least the 8 years I was there. I know the tool shop that was doing must of the work for them is still using the same program.

Thanks toolman801.

In fact, my main problem due to family molds has nothing to do with nr of cavities. The issue is that i have n diferent codes of parts multiplyed by the nr of cavities per each part code.

Doing the production declarations, they declare X parts of code A + X parts of code B + ....

This works like this 'cose IFS only works with 1 production order per code, and not per mold.

So.. i'm thinking that i haave no choice beside checking mold to mold what is the nr of part codes per mold and after that, do some statistical analisys to determine the aproximated shots of the mold, comparing with the parts declared.

Occurs to you any other simplier ideia?

How is your shot count data being entered into your maintenance program?

The data is aquired from the machine value, and entered in our internal system database. The nr of cavities is another value entered. The problem is how the values are treated inside the sotware.

We have to make 1 production order per each part code produced in the mold. The system works well for single cavity molds and multicavities os the same part molds.
In molds with more than 1 part code per shot... the problem arrives. The parameter (counter inside software) is increased as many times as the nr of diferent part codes in the mold.

Is it possible to add a suffix to the mold numbers that are family tools? If so, create your main tool number in then the family number (ei tool number 8104 becomes 8104, 8104a, 8104b) for a 3 part family tool. Set the maintenance system to maximum shots between PM's on the subletter molds.
You will have to reset your main system to send the family part numbers to the new mold numbers.
I know in SAP software this took a order from "God" but we were able to make it happen.
